It would be if it was only added for this one filter. If a post 
processing engine already exists, I think a post process filter is a 
better choice than a separate special-purpose feature.

And if one doesn't exist, I think adding one would still be a better 
idea. It solves more problems with less work than adding tons of little 
one-use features.
